Is Pineapple keto?
Not keto-friendly 19.3 g net carbs per one cup of chunks (165 g) — 97% of a 20 g keto day.
Short answer: Not in normal portions. One cup of chunks (165 g) of pineapple: 19.3 g net carbs — 97% of a strict 20 g keto day — with 0.2 g fat and 0.8 g protein.
Pineapple is sweet, low in fibre and usually eaten in generous portions — the combination that pushes it out of a keto day.
How pineapple fits a keto carb budget
On a 20 g day, one serving uses 97% of your budget, leaving 0.7 g for everything else. Measure portions rather than eyeballing them.
Worked example. 165 g of pineapple = 21.6 g total carbs − 2.3 g fibre = 19.3 g net carbs, 0.2 g fat, 0.8 g protein and 83 kcal.
If you still want some, plan it: a strict day is 20 g, and how net carbs are counted explains why the fibre here does not rescue it.
